ARTIFICIAL FUEL.

SPECIFICATION forming part of Letters Patent No. 746,668, dated De b 15,1903. Application filed March 12, 1903. Serial No. 147,515. (Nospecimens.)

To all whom it may concern.-

Be it known that I, FRANCIS J. BULAsK,a citizen of the UnitedStates,residina at Toledo, in the county of Lucas and State of Ohio,have invented certain new and useful Improvements in Artificial Fuel, ofwhich the following is a specification.

Artificial fuel in the form of briquets or lumps manufactured inaccordance with this invention when burned cokes preliminary to passinginto ashes, being free from elinkers a thin or softidough; This dough iscombined with the combustible material in a mill or in any way to insurea thorough mixing of the materials, so that when pressed together theparticles will adhere. A small quantity of alum is sometimes added tothe binder; also, a small percentage of sulfuric acid to convert theflour into deXtrine. To increase the solidity and hardness of thebriquet,a quan-- tity of plaster-of-paris, soaked in a saturatedsolution of alum, allowed to set, baked in an oven and ground to apowder, is mixed with the combustible material prior to adding same tothe flour dough or binder.

When the combustible material consists of beet-pulp, fruit, sugar-cane,or other refuse containing saccharine matter, the latter is carbonizedin the process ofcombustion, thereby adding to the efficiency of thecomposition as a fuel.

Having thus described the invention, what is claimed as new is 1. In anartificial .fuel, a binder for the combustible material, containingflour and a solution of potash or soda and plaster-of-paris soaked in asaturated solution of alum, al-

lowed to harden, baked and ground, in sufficient quantity to make athindough, substautially as specified.

2. An artificial fuel, consisting of combustible material and sodiumchlorid and a binder of thin dough, same consisting of flour and asolution of potash or soda and plaster-ofparis soaked in a saturatedsolution of alum,

allowed to harden, baked and ground, in suf-' ficient quantity to make athin dough, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.V
